https://en.wikipedia.org/wiki/Basis_set_(chemistry)The most common minimal basis set is STO-nG, where n is an integer. The STO-nG basis sets are derived from a minimal Slater-type orbital basis set, with n representing the number of Gaussian primitive functions used to represent each Slater-type orbital. Minimal basis sets typically give rough results that are insufficient for research-quality publication, but are much cheaper than their larger counterparts. Commonly used minimal basis sets of this type are:

Base STO-nG — Wikipédia
https://fr.wikipedia.org/wiki/Base_STO-nG- Pour ces bases minimales, les orbitales de cœur et de valence sont représentées par le même nombre de fonctions primitives gaussiennes Φi. Ainsi, les éléments d'une base STO-3G pour les orbitales 1s, 2s et 2p de l'atome de carbone sont tous des combinaisons linéaires de trois fonctions gaussiennes primitives. On a par exemple une orbitale de cette base STO-3G donnée …

STO-nG basis sets are the minimal basis sets, where 'n' represents the number of primitive Gaussian functions comprising a single basis set. For minimal basis sets, the core and valence orbitals are represented by same number primitive Gaussian functions . For example, an STO-3G basis set for the 1s orbital of H atom is a ...
